Dave Green is a London based artist who creates simple line drawings in his lucid dreams which he re-creates upon waking up. Lately he has been experimenting with giving his pen and paper to other people in his dreams to see what they create. His art has been featured in BBC Science Focus and DreamTime magazine. He has lectured about his work at Tate Modern and is the subject of a documentary by The World Science Festival called 'The Dreaming Pen'
